We offer Iodine Crystals in different quantity to cater diverse demands of the clients. Iodine is produced commercially from iodine-containing brines. Natural brines, or brines extracted from oil wells containing up to 150 mg per litre (0.02 ounce per gallon) of iodine. Impurities, such as clay, sand, and oil, are removed by filtration, and the solution is passed through a stream of sulfur dioxide and then through a number of containers holding bundles of copper wire. The copper iodide that forms is removed by filtration, washed with water, dried, and finely ground. The product is heated with potassium carbonate to give potassium iodide, which is then oxidized to the free element with dichromate and sulfuric acid:
